Assuming you've done a "make install", pkg-config will tell you the
cflags and libs you need to use.  You'll need to have your
PKG_CONFIG_PATH set correctly for this to work.  If you installed into
the default prefix (/usr/local), the you'll need either:

$ export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig

  or

$ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

Depending on whether you're on a 64-bit machine and/or what OS and
distribution you're using

On my x86_64 machine running Fedora 13:

$ echo $PKG_CONFIG_PATH
/usr/local/lib64/pkgconfig


$ pkg-config --cflags usrp
-I/usr/local/include
$ pkg-config --libs usrp
-L/usr/local/lib64 -lusrp -lusb
